Hello Mrs, Welcome to Health Care Magic. I understand your concern. The drug your treating doctor prescribed belongs to a family called statins. As all the drugs, Simvor (simvastatin) has side effects, which include abnormal laboratory test results, liver problems, muscle problems (pain, tenderness, or weakness), headache, constipation, stomach pain or indigestion, mild nausea, dark coloured urine, pain or burning when you urinate etc. I don t know what your altered level of cholesterol is, but if I was your treating doctor, I would suggest you modify your diet and lifestyle. You can try to limit fat from your diet and instead begin a diet rich in fibres (plenty of fresh fruits and vegetables), rarely having red meat, but mostly chicken and fish, as well as everyday physical activity. I would recommend you also to use healthier cooking methods (Baking, broiling and roasting). Hope I answered to your question. Take care, Dr. Ina Zaimi
